Specific challenges in the application of fibre-metal laminates

Fibre-metal laminates as a combination of metals and fibre reinforced plastic materials are investigated in a variety of current research projects. The intention of combining these two different materials is the compensation of their inherent weaknesses. However, their application as multi-layered laminate is also accompanied by a wide range of challenges, as DLR and TU Braunschweig scientists describe.
Intrinsic Hybrid Laminate
Fibre reinforced plastic (FRP) composites meet the requirements of many different lightweight applications due to their extraordinary weight-specific stiffness and strength as well as their marginal fatigue. However, they also show some major weaknesses like low bearing strength or brittle failure properties. Fibre-metal laminates (FML), consisting of fibre reinforced plastic and metal, are often investigated with the aim to overcome these weaknesses. Although many different definitions for FML can be found, the major difference to hybrid structures or...
The presented findings were essentially gained during the project no. 8 of the ’Schwerpunktprogramm SPP1712’ funded by the ’Deutsche Forschungsgemeinschaft’. The authors like to thank for funding and support. Another word of thanks is addressed to Salzgitter Mannesmann Forschung for providing material.
